The Effects of Participation in Decision-Making on Worker Satisfaction and Productivity: An Organizational Simulation1

Although correlational evidence of a positive relationship between participation in decision-making and satisfaction is relatively consistent, whether participation in decision-making has a causal effect on satisfaction remains unclear. The present research examined, through an organizational simulation in which high and low levels of participation in decision-making were manipulated, the causal effect of participation on satisfaction and productivity. The subjects were 128 male undergraduates randomly assigned to 32 four-person groups. Results of the experiment showed that participation in decision-making had a significant positive effect on satisfaction. In addition, the correlation between perceived influence and satisfaction was positive (r= .31). Contrary to theoretically derived predictions, participation had no impact on productivity.     

Stimulus specificity in avoidance learning

The present experiments address the issue of stimulus specificity in fear and avoidance learning. First, it was established that light stimuli are effective warning signals (WS) in shuttle avoidance. Then light stimuli were shown to produce conditioned suppression in the conditioned emotional response situation comparable to that produced by noise conditioned stimuli. Finally, the effectiveness of noise onset and noise offset as feedback signals was tested. This was assessed under conditions of immediate and delayed termination of a light WS. Delayed termination of a light WS interfered with avoidance learning and the introduction of noise offset as a feedback signal enhanced it. The only demonstration of stimulus specificity was the failure of noise onset to function as a feedback signal.     

Amnesics Have a Disproportionately Severe Memopry Deficit for Interactive Context

Two experiments were used to compare the recognition memory of amnesic and normal subjects for intentionally encoded words (targets) and for incidentally encoded words that were meaningfully related to the targets and presented at the same time (interactive context). In both experiments the target recognition of the two groups was matched at a high level by presenting the amnesics with much shorter lists of words to remember. Experiment 1 compared 20 amnesics and their matched controls and showed that whereas the amnesics' recognition of the target words did not benefit significantly when they were presented together with their interactive context words (relative to their recognition when the target words were presented alone), that of the controls did. Experiment 2 compared 14 amnesics and their matched controls and showed that when patients and their controls were matched on their target word recognition in isolation, then the patients still showed worse recognition for the interactive context words. These effects were not found only in Korsakoff patients, and their size did not correlate with behavioural measures of frontal-lobe damage. It is concluded that amnesics may be more impaired at recognizing incidentally encoded interactive context than they are at recognizing target material, and this deficit may be an essential feature of the syndrome.     

The Family Stress Model as it Applies to Custodial Grandfamilies: A Cross Validation

There is scant research on how the parenting practices of custodial grandmothers affect the psychological adjustment of grandchildren in their care. Yet, the findings from a handful of prior studies suggest the relevance of the Family Stress Model (FSM) to these caregivers. The present study further tested the FSM with baseline data from 343 custodial grandmothers (M_age?=?58.5 years) enrolled in a clinical trial of the efficacy of interventions for improving the well-being of their families. Not only was this “help-seeking” sample atypical of prior FSM studies, but also unique to the present study was our addition of multiple parenting practices, self-reported and clinical ratings of grandmothers’ distress, and reports of grandchildren’s internalizing and externalizing difficulties from grandchildren and grandmothers. Mplus 7.31 was used to test a model where the effect of grandmother distress on grandchildren’s internalizing and externalizing difficulties was hypothesized to be indirect through five distinct parenting practices. The findings regarding both the measurement and structural models fit the observed data well, and invariance was largely found across grandchildren’s gender and age (4–7 vs. 8–12). Although grandchildren’s self-reported internalizing and externalizing difficulties were unrelated to grandmothers’ distress and parenting practices, the grandmothers’ reports of these outcomes were generally related to their own distress and parenting practices as hypothesized. However, considerable variation was found across the five parenting practices in terms of their relationships to the other FSM constructs. We conclude that data from multiple informants and measures of assorted parenting practices are essential to future research and practice.
